preview_shinyCV.R

#' @title shinyCV viewer.
#' @description Launch a shinyCV web application to display your beautiful CV before
#' exporting it to shinyapps.io via \code{\link{publish_shinyCV}} or on a private
#' shiny server.
#'
#' @param cv_path The directory where your CV is stored
#' @param cv_mode The content to display in the CV. There are currently 5
#' flavors:
#' \itemize{
#'  \item \code{"basic"}, which will display only formation and projects
#'  \item \code{"academic_light"}, which will display formation, projects, and teaching
#'  \item \code{"academic"}, which will display formation, projects, teaching and talks
#'  \item \code{"research"}, which will display formations, projects, publications and talks
#'  \item \code{"full"}, which will display the 5 tabPanels, namely formation,
#'  projects, teaching, publications and talks
#' }
#'
#' @param data_source There are 2 flavors:
#'  \itemize{
#'  \item \code{"manual"} : it means that datas need to be generated as in the example
#'   of \code{\link{feed_shinyCV}}
#'  \item \code{"from_cvbuilder"} : If you previously filled your CV
#'  with \code{\link{build_shinyCV}}
#' }
#'
#' @param datas 2 flavors:
#' \itemize{
#'  \item \code{NULL} (default) : If data_source is "manual" and if datas are NULL, an
#'  example is generated
#'  using \code{\link{generate_datas_shinyCV}}, so that you can still see how
#'  a full CV looks like
#'  \item \code{your_datas} : if datas are not NULL and data_source is "manual",
#'  datas should have the same structure as
#'  that in the list of datas returned by the \code{\link{feed_shinyCV}}
#'  function (see examples below)
